1KSMBJ8.2CA Application Field and Working PrincipleTVS-Diodes provide an excellent solution for suppressing ESD, surge, over voltage and transient electrical surges and spikes. They are often used to protect a wide range of systems and applications, including communications, power supplies, computers, networks, medical, industrial, automotive and military/aerospace. The 1KSMBJ8.2CA is a TVS diode specifically designed to protect against transients in high-frequency, high-speed applications such as CATV, HDTV, wireless and other digital systems. The 1KSMBJ8.2CA is a single line device-unidirectional, and consists of two complementary silicon avalanche diodes, moulded in a monolithically integrated chip packaging which provides high ESD protection. It also provides optimal protection against low and medium energy transients, and is suited for both AC and DC power lines. It has excellent thermal stability, and is suitable for use in high temperature environments. The 1KSMBJ8.2CA is ideal for providing protection against transients up to 8.2pF. Its working voltage is between 5V and 20V DC, and its peak pulse power is rated at 15W. It also features a low (max) capacitance of 0.3pF (2VDC), and a high maximum surge current of 150A. It is capable of. The 1KSMBJ8.2CA works by clamping high-energy transient voltages and current levels to an acceptable level, typically 15V (Breakdown Voltage) or less. It does this by providing an avalanche breakdown when a high voltage is applied. When the applied voltage reaches the avalanche breakdown voltage, a large current begins to flow from the cathode to the anode. This is the avalanche breakdown current. It is this current which protects the device from any further damage, often preventing total device destruction.In addition, the 1KSMBJ8.2CA provides reverse-circuit protection. This means that it will activate and protect the device from transients flowing in the opposite direction, thus providing extra protection from potential short circuits.In summary, the 1KSMBJ8.2CA is an excellent TVS-Diode that provides excellent protection from transient voltages and current levels. It is ideal for a wide range of communications, power, medical, industrial, automotive and military/aerospace applications. It uses an avalanche breakdown to safely clamp the voltage and current levels, and provides reverse-circuit protection. It is a robust, reliable solution that offers excellent performance and long-term protection from extreme voltage fluctuations.
